RAIL ANCHOR.

Application filed April .3, 1922. Serial vNo. 549,019.

.To all (whom itmay concern):

Be it known that 'I, .LAURENQE J. BERKE- LEY, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee 5 and State of Wisconsin, have invented certain new and useful Improvements in Rail Anchors, of which the following is a specification, reference being had to the accompanying drawing, forming a part thereof.

This invention relates to devices for preventing the longitudinal creeping movement of railway rails.

Its main objects are to provide a simple and strong device of this class which can be quickly and easily applied torails and when applied will be effective and reliable in operation; which will not be loosened by the passage of trains or by changes in temperature; which will readily. adapt itself to ordinary variations in rail :bases; the grip of which on the rails will be tightened by a slight longitudinal displacement of the rails on the ties; and generally to improve the construction and operation of devices .of this class.

It consists in the construction; arrange ment and combination of parts as hereinafter particularly described and pointed out in the claims.

In the accompanying drawing like charactersdesignate the-same parts in the several figures.

chor on the line .6-6,

Referring to Figsl to 8 inclusive, showing a preferred embodiment of the invention, the anchor comprises a rigid bar or yoke 1, adapted to span or extendacross and fit the under side of a rail bnseQ, and

formed or provided at one end with a jaw 3, fitting over one edge of the rail base and at the other end opposite the other edge of the rail base, with a fulcrum seat or key bearing 4. It is also formed adjacent the bearing 4: and belowthe' top of the=bar with a key deflecting and straining bearing 5. preferably formed with a convex or inclined face for engagement with a spring key to facilitate forcing the key into place, as shown in Fig. 1, and as hereinafter explained. The bar or yoke 1 may be madeof malleable iron,

and for the sake of strength and lightness, is preferably flangedorof channel shape in cross section. It is formed in the web between the key bearings 4 and 5. with an opening to receive thekey and at or adjacent one end with a laterally. projecting abutment 6, for engagement with the side of a tie 7, as shown in Figs. 2 and 8. The

abutment 6 is preferably formed as shown in Fig. 2, with a convex or rounded face, for proper and effective engagement with the tie when thebar or yoke assumes different positions on the rail base. The abutment 6 is braced and strengthened by a vertical web onfiange 8, disposed transversely to the bar 1. i

vA spring key v9, preferably of tapering and bowed .or curved shape. as shown in Fig. 1 is adapted to be inserted and sprung or forced transversely to the length of a rail into place between the fulcrum seat or hearing 4: and the opposite edge ofthe rail base and against the deflecting and straining bearing 5 and when the parts of the anchor are assembled on a rail base, as shown in Fig. l, toexert a yielding pressure against the rail base towards the .j awSQthereby subjecting the bar or yoke 1' to tension tending to draw the aw towards the key and to yieldingly grip the rail base between the jaw and the key with suflicient. force under varyingconditions, to prevent the bar or yoke I The'key 9 isformed in the inner edge adjacentitslarger endifwith a notch to engage with the upper corner of the adjacent rail base flange and hold it in place thereon.

To apply the anchor to a rail, the bar or yoke 1 is placed underneath the rail base with the abutment 6 against the side of a tie, and the jaw 3 is driven or forced transversely to the rail into engagement with one edge of the base, with the top of the bar against the under side of the rail base.

The larger end of the key 9 is then forced upwardly with a special tool or otherwise, between the other edge of the rail base and the fulcrum seat or bearing 4t with the smaller more flexible end of the key, against the bearing 5, till the notch 10 snaps into engagement with the upper corner of the rail base. The smaller end of the key being thus forced upwardly against the bearing 5, sub jects the key to tension or strain, tending to tip its wider end inwardly and downwardly and to cramp and hold it tightly between the opposing bearing and rail base. A slight longitudinal movement of the rail towards the tie with which the abutment 6 engages, carries the key 9 with the adjacent end of the bar or yoke 1 towards the tie, thereby turning the bar into a position more or less oblique to the rail base and increasing its grip thereon, the end of the bar or yoke with the jaw 3, being prevented from advancing with the rail towards the tie. by the abutment 6.

The initial yielding grip of the anchor on the rail base produced and maintained by the spring key 9, prevents the anchor from becoming loose and from being shifted back out of engagement with or operative relation to the tie by the jarring effect of passing trains or other causes, and com.-

pensates for ordinary variations in the width and thickness of rail bases.

Referring to Figs. 4 and 6 inclusive, il illustrating a modified construction of the anchor, the tie abutment 6 is formed on the end of the bar or yoke 1' opposite the jaw 3, and is provided with the key deflecting or straining bearing 5, which may be cast. integrally with and form a part of the abutment reinforcing web or flange 8'. The tapering spring key 9' is substantially straight or but slightly curved, and may be driven or forced downwardly or upwardly into place between the fulcrum seat or hearing 4 and the opposite edge of the rail base,

against the bearing 5, by which it is defiected and strained. Adjacent its smaller end the key may be slightly bent or recessed, as shown at 11 in Fig. 4, to engage'with the lower edge of the bearing 5 and thus prevent accidental displacement of the key up wardly after it'has been forced into place.

In other respects the construction. of-this form of anchor is substantiallylike that of the form shown in Figs. 1 to 3 inclusive,

over one edge of the rail base and at the other end with key bearings, and a spring key adapted to be inserted and forced transversely ofthe railfinto place against said bearings and the other edge of the rail base and acting when in place .to grip the rail base between thej aw and key with yielding,
